Yes, I am now in my 16 week but I had the same symptoms for about the first 7 or 8 weeks. It stopped for a while but now the symptoms are coming back, just not as bad.
It's very normal. Try a heating pad. This is my third pregnancy, and it is the only thing that has helped. If you really are concerned, go to an urgent care. They usually don't treat pregnant women, but since you are so early, and you don't have an obgyn yet, they will help you.
Its yur uterus strectching and the other can be maybe the sciatica or however u spell it.
